17' Claims. (01. 210-25) This invention relates to improvements incordless electric sadiron assemblies--assemblies in which the iron,designed to be heated electrically, has no direct cord connection withthe current supply, but receives its current through the rest upon whichthe iron is seated during the ironheating period.

Electrically-heated sadirons are well-known commercially, the ironcarrying one or more heat ing elements installed therein, the ironcarrying a suitable cord connection which permits ready attachment to asocket fixture to complete a current supplying circuit to the heatingelement. Such structures, while efficient, havethe disadvantage of thetendency to tether the iron by the length of the cord, with the corditself tending to hamper the'free ironingoperation by its presence.

The present invention is designed to obtain theadvantagesaccruing'through the use of electric heating-of the element,but eliminate the disadvantages of the cord presence during ironingoperation. Since a cord connection is essential to obtain the currentneeded for the element hea ing, this is carried by the rest upon whichthe iron is seated while being heated. This leaves the heated iron freefrom cord connection when removed from-the rest and ready for servicethus providing the untrammeled serviceability available with a sadironheated by a separate source :7

and, in addition, having the advantages of the rapid and controlledinternal heating that is present with the installedelectrically-activated heating element. The change involves a number ofproblems requiring solution.

For instance, since the heatingelement is internal of the sadiron, thecurrent for. activating the element must be brought to the element froman external source, inasmuch as the sadiron is to be free of cordconnections; the rest for the iron carries connections with a source ofcurrent supply; hence, theproblem of extending the current path from therest to the interior of the sadiron without the use of cord connectionsis prescut. This is the fundamental problem, but its solution involvesmany. correlated problems due to the fact that electric current is beingutilized, these involvingthe use of contacts which must-be madeoperative to provide a complete circuit; the

need for preventing short-circuits; the isolationor the current path toprevent electrification of the body of the iron by current activityduring element heating; control of the heating temperature ofthesadiron; automatic limitation-oi current supply to periods when thesadiron is in po- 2 sition for heating with a manual control present todetermine when the heating shall take place when the ironin its positionfor heating. These are a few of the problems involvedin solving thefundamental problem, others occurring in attempting to solve theseand'other conditions.

The present invention has for itsprincipal objects the construction'of asadiron assembly (a sadiron and its rest) designed to solve these andother incidental problems the solution of which is essential inproviding a sadiron capable of being heated electrically by an internalheating element'but which, for ironing purposes, is free from cordconnections witha sourceof current supply. The details of the problems,the way of solving them, and the means employed insolving them inthisway, are set forth in detail.

To these and other ends, therefore, the nature of which will be moreclearly understood as the invention'is herein disclosed, said inventionconsists in the improved constructions and combie nations of partshereinafter more fully described, illustrated in theaccompanyingdrawings, and morepa-rticularly defined in the appended claims.

The sadironof the present invention is shown more particularly inFigures 1, 2,"? and 8 and has its general configuration conforming tothe'type in which" the front. end isqpointed with :the rear end blunt.structurally, however, it differs materially from the usual irons ofthis type, due to the fact that the active ironing surface-the undersurface of the heel-is not an integral formation as in the commercialsadiron structures, although the ironing surface is itself a continuousface, the heel zonewhich substitutes for the usual sole-plate beingformed in two parts 55 and I6 which are connected together as byinsulated bolts H with an intervening insulating element 18 which may bemica or insulating fibre or the like-to thereby insulate one of theparts from the other. The division between the parts is longitudinallyof the heel, and is preferably in a straight line, but can obviously bevaried from a straight line as long as the opposing configurations ofthe division are generally complemental to each other.

The peripheral contour of each. of the heel parts l and It presents anupstanding peripheral portion Ifia, Ilia, this being of suitable heightand of such cross-sections as to provide a stable heel constructionperipherally with the inner wall 16b, forming the vertical wall of theheating element chamber which is located internally of the heel. Whilethe remaining vertical side of each of the parts l5, lG-the mating ordivision sidemay be flanged from front to rear, if desired. I prefer toutilize only sufficient fianging as may be needed to assure stability atthe opposite ends of the division line and such upstanding members aswill provide proper connection by the bolts ll, thus leaving theinsulating element It generally exposed at this side of each of thechambers. This provides an advantage through reducing the amount ofmetal required, but the greater advantage lies in the fact that thisWall of the chamber is thus made mostly non-metallic-other than theupstanding flange portions or lugs 59 through which the bolts I! pass insecuring the parts together and thus reduce the possibility of theheating element 20 being affected through accidental contact thereofwith a metallic portion of a heel part.

The heating element 20 is metallic and positioned within such heelchamber-the latter being closed by a layer of insulation, such, forinstance as mica sheet 2! overlying the chamber. Said element 20 has oneof its ends secured to a contact 22 located in an end zone of thechamber of heel part l6, and then extends in a more or less sinuouscourse to the opposite end zone of such chamber, where it passes throughan opening in element l8 to the chamber of part 15 in which it extendsin a more or less sinuous path to the opposite end zone of such chamber,thus traversing the major portions of the length of both chambers; ifthe heating circuit is not to be subjected to temperature control, theend of the element is secured to a contact located in such latter endzone.

However, it is preferred to include a temperature control in heating thesadiron, and in such case, the latter end of the element is connected toa supporting member 2a.. The temperature control, indicated at 25, is ofwell-known construction-operating on rheostat principles-and is notspecifically disclosed other than as shown, involving a rotatable shaftoperated by a control knob, with the shaft extending into the chamber ofpart 15, the latter chamber carrying the control elements and theconnections to the control elements from member litand from such controlelements to a contact 26, the rheostat controlling the passage ofcurrent through the heating element 20, thus controlling the tem- 4peratur of the iron; the device 25 carries indications expressive of thecharacter of material being operated upon, and by setting the controlknob on the proper indication, the iron is brought to the desiredtemperature.

The contacts 22 and 25 are each of suitable formation and extendvertically through openings in the planar portion of the heel parts, thelatter carrying openings to permit this as well as the passage ofinsulating members 21, the exposed ends of the contacts and members 21lying in the plane of the ironing surface of the heel and thuspractically form small areas of such surface. As can be understood, thecontacts and insulating members may be of any preferred structure, eachcontact including a formationthe usual screw, for instance--permittingthe element 20 to be removably secured to the contacts, properinsulation being utilized where essential.

In sadirons in which the temperature control is omitted, contact 26 willbe located in the position of supporting member 24.

Above mica sheet 2 I, is located a heat-storage plate 28, preferablyformed of copper, this plate being secured to the body of the heel parts[5, [6, by screws 29, properly insulated, the body having suitablebosses to receive the screws, the latter passing through the plate 23and sheet 2!. And overlying the plate 28 is a shielding cover 3! of adesired configuration, the edges of which are mounted in the peripheralzone of plate 28- the latter being stepped for the purpose; the cover issecured to plate 28 by suitable screw mountings 3|. The temperaturecontrol button and indicating formation are exposed above the cover. Thecover not only serves as a closure for the plate 28, but also as a meansfor securing a handle 32, the latter having a suitable configuration,with its rear end carrying an operating formation 33 presently referredto in detail, and, if desired, being provided with an indicating meanshaving connection with the circuit of the heating element. For instance,the handle may have a vertical opening 32a the top of which is closed bya suitable indicator such as a ruby lens 34. In opening 32a beneath thelens is a small lamp and reflector unit 35, the connections of whichextend downward through cover 30, plate 28, and sheet 2| into theheating element chamber of the heel, where connection is made with thecircuit, as by attachment to contacts 22 and 26, thus setting up aparallel relation with the heating circuit, the connections carrying theproper resistance conditions to assure proper operation of both parallelpaths of the circuit. Obviously, when the heating element circuit ismade active, this activity will also extend to the lamp, thusilluminating lens 34-providing visible indications of the activity ofthe heating element circuit.

As is apparent from the above description of the sadiron, it is equippedwith the element structures capable of providing a controlled heating ofthe iron, but it lacks a current supply for activating the heatingelement. It presents a pair of exposed contacts by which currentconnections could render the heating element active with the contactscarried by heel parts insulated from each other and into both of whichthe heating element extends. And if the heating element is activated tothe desired extent, the iron becomes heated and contains a heatedbody-the copper plate-which will serve to retain the iron heated for aconsiderable period. But, as thus far described, the iron is totallyfree of electrical connections or a supply of electricity for activatingthe heating elements. In other words, the iron, when heated, has thefreedom of action possessed by irons heated by an external source,although the iron contains the elements required to give it theadvantageous heating conditions presented by electric heating; the iron,in service, has these elements totally inactive, and incapable of beingmade active during service, thus eliminating any liability of dangerfrom electric current during such service.

Activity of the heating element can be had only by positioning the ironin definite position on a rest or support which will now be described.

The base of the rest or support is, structurally, arranged in twogeneral zones (Fig. one of these (zone A) being for the positioning ofthe sadiron for its heating activities, the other (zone B) providing asupport for the structures designed to controllably supply the currentfor such heating activities, the zone B being indicated as in rear ofzone A. Since the invention contemplates completion or the circuit tothe heating element only when the sadiron is in a predetermined positionon the rest, and also contemplates that the rest should also beprotected as far as conveniently possible against undesired accidentalcompletion 'of the circuit as well as the possibility ofshort-circuiting conditions, the two zones have more or less specialcharacteristics. The rest is not completely fool-proof, but thearrangements are such that departure from the normal regimen ofoperation must be by deliberate action and therefore intentional.

Zone A is preferably formed in two parts 36 and 31, these being arrangedside by side and spaced by insulating element 38 along the longitudinalaxis of the zone; each part forms approximately one-half of the supportfor the sadiron, and the two parts are secured together to complete suchsupport. The side peripheries of the two parts thus combinedly presentthe general contour of the similar peripheral zones of the sadiron, butpreferably of increased dimensions, thus permitting the presence of anupstanding insulated formation 39 designed to partially overlie one ofthe heel portions of the iron and aid in retaining heat in the iron; theformation 39 may be omitted if desired, but its use is preferred sinceit aids in a more rapid heating of the iron by tending to reduce heatdissipation, and to conserve the iron heat when the iron is simplyresting on the support. As with the sadiron construction heretofore setforth, the two-part base of the zone tends to prevent short circuitingof the circuit in the base.

Secured to the upper surface of each part 36 and 31, and preferablyinsulated from the part, is a strip contact which extends longitudinallyof the part-contact 40 for part 36, and contact 4| for part 31. Contacts40 and 4| are individual to the part by which they are carried and areeach of suitable length. For instance, contact 40 is designed toco-operate with contact 22, while contact 4| co-operates with contact26; hence, the length of the contacts 4|] and 4| will depend somewhat onthe positions of contacts 22 and 26 when the iron is in position forheating element activitythe length may, and preferably does exceed thatneeded to ensure conta'ct relationship in such definite position, sinceit is desirable to meet the possibility of different locations ofcontacts 2-2 and 26 in different irons.

Contacts 40 and 4| may be secured in position in any desired mannei -asby embedding or being above the top plane of the composite base-but itis preferred that each contact be insulated from the part by which it issupported, it being understood, of course, that it is so positioned thatwhen the sadiron is properly seated on the rest, the contact 22 willhave definite contact relationship with contact 40, while contact 26will have a similar relationship with contact 4|. While contacts 40 and4| are shown as having this portion as of strip form, it is apparentthat this may be varied; for instance, the zone A construction may bedesigned to have the sadiron rest upon an insulating surface such as amica-sheet; in such case, the contact strips would underlie the sheetand be formed with upwardly-extending projections extending throughopenings of the sheet, thus tending to set up the conditions of spotcontacting; this particular structure is indicated in Figure 4, in whichthe mica sheet is indicated at 42 and the projections at 43.

Contacts 46 and 4| each also include a vertically extending leg-40a andMa, respectivelythese being of a suitable height, and each beingequipped with a contact-point 44-which may be platinum-facing away fromthe positioned iron. The vertical legs are positioned in rear of theheel of the positioned iron, thus actually reaching into zone B of therest; they are also spaced apart sufliciently to permit magnetic member33 to move to operative position between their locations in positioningthe iron.

For accurately positioning the iron on the rest and ensuring propercontact conditions, the parts 36 and 31 have their rear zones eachprovided with an upstanding formation into which :parts of the rear zoneof the iron may pas's and be guided into position, thus tending to serveas a keeper structure. For instance, a rear zone of the side peripheryof a part may have a vertically extending portion 45 of suitable depthand having its top formed with an inwardly extending flange 450..Similarly, the rear periphery carries a vertically-extendingportion-which may be inclined-46. When the iron is placed in position onthe rest, the rear of the heel will contact portion 46 with the flange45a. overlying cover 30; if desired, the flange may be shaped to forcethe iron into close contact with the rest, but, generally, the weight ofthe iron is sufficient to assure proper contact. As will be understood,portion 46 is provided with a suitable opening for the free passage ofcontact 40 or 4| without liability of flow of current between thecontact and portion 46, the portion 46 being divided, as shown, toaccord with the division between parts 36 and 31.

The zone B is located in rear of zone A and serves as a support forcertain circuit make and break structures presently described, thesupport being in the form of a base 41 the side contours of which mayform a general continuation of the peripheral sides of parts 36 and 31,the fore and aft dimension being sufficient to properly receive andposition the elements carried thereby. Since base 41 is continuous fromside to side, it preferably has an insulated status relative to parts36., 31, as by the use of an insulating material in its manufacture, oran actual insulating member interposed between it and such parts 36 and31, or is spaced from the latter, thus retaining the dividedcharacteristic of parts 36 and 31.

The base 41 is positioned by a member 48 within which the sides and rearof the base are mounted in secured relation to the member, the latterhaving forwardly-projecting extensions 48a.

which overlie the rear zone of the peripheral side of the parts 36 and31, being secured to and insulated from such parts, as by screws orbolts 49, thus anchoring the base relative to zone A. Member 48preferably is of a height to extend materially above the top plane ofthe base, and may include a suitable cover formation to overlie theoperating mechanisms carried by the base. If used, such formation may beof different types, such as by wings extending inward from the sides orby a hood-like structure, or by other forms, which are more or lessobvious, the purpose being mainly for protection of the user againstaccidental contact with the electrical mechanisms mounted on the base oraccidentally providing closure of circuits which are normally open.Since an element of such mechanisms is a manually-operated switch, theformation, especially if of hood form, is provided with an openingsufficient to permit ready manipulation of the switch through theopening.

Mounted to oscillate above base 41 and supported by member 48, as by ashaft 53, is a contactcarrier the shaft extending lengthwise 0f thecarrier and in the upper edge zone of the latter, the carrierpractically depending from the shaft. The carrier is of less length thanthe length of the shaft 53 but greater than that of the spacing distanceof contacts 43 and 4|, the shaft preferably carrying light springs 52intermediate the carrier ends and the sides of member 43 with themounting arranged to swing the carrier-depending portion rearwardlyabout the shaft axis through a limited range of movement, suitable meansbein provided for limiting the range of movement un- .der spring action.

The end zones of the carrier are each provided with a contact formation53 positioned to partake of the oscillating movements of the carrier,these contacts being positioned opposite the platinum contacts 44 sothat when the carrier is swung forwardly in opposition to the springaction, contacts 53 will be moved into contact engagement with contacts43 and 4| through contacts 44. Intermediate contacts 53 the carrier isprovided with a suitable formation designed to co-act with member 33along the lines of a magnetic relay. The formation may be in the form ofone or more soft metal plates 54 (Fig. 6) mounted on the carrier, thusforming a body capable of being influenced by a magnetic body in suchmanner as to swing the carrier on its axis forwardly from its normalrearward position, and thus bring contacts 53 into engagement withcontacts 44.

Ihe magnetic body for providing this swing of the carrier is the member33 which has characteristics of a permanent magnet of sufiicient powerto influence the pseudo armature formed by the plate formation 54, whenthe member 33 is brought to the vicinity of such plate formation. Sincemember 33 is carried by the sacliron handle in position such that whenthe iron is placed on the rest and moved rearwardl into engagement withportions 45, member 33 will then be in such vicinity of the armature(Fig. 8) the armature does not reach actual engagement with member 33,contacts 53 engaging contacts 44 prior to actual engagement of thearmature with the magnet and thus limiting the forward swing of thecarrier and providing a sustaining magnetic field for maintaining thecarrier in the forwardly-swung position. The length of the carrier andthe positions of contacts 43 and, 4| are so arranged that a permanentmagnet of proper dimensions positioned symmetrical to the longi- 8tudinal axis of the iron will freely enter into the zone intermediatethe contacts 43 and 4|. The magnet 33 is fashioned to avoid collectingof materials on its surface.

The base 41 also carries a supporting member in rear of and spaced fromthe carrier, member 55 carrying a suitable manually-operated switch 56together with a pair of insulated posts 51 and 53 arranged for securingcurrent connections, these posts respectively having a flexibleconnection leading individually to the respective contacts 53, theflexibility of the connections permitting the free swing of the carrier;post 51 also has a lead connection with switch 56, the opposite terminalof the switch leading from the source of current supply represented byplug 59; the post 58 is connected directly to such source. The cordconnections between the plug and the switch and post 58 are of the usualtype, passing through a fixture carried by member 48.

As will be understood, the arrangement of the rest is such as to besubstantially free from accldental circuit activation. To secure thelatter, switch 56 must be closed, carrier 5| must be moved to completeengagement of contacts 53 and 44, and a metallic member permitted tobridge the contact strips 43 and 4| if there is a break at either ofthese points the circuit cannot be established. While it might bepossible to drop a metallic connection across contacts 40 and 4|,springs 52 will hold the carrier in rear position excepting underintentional advance, and even if switch 55 were inadvertently leftclosed, breaking of the circuit at contacts 53 and 44 would preventcircuit activation excepting it to be intentional.

When the sadiron is placed on the rest in position for heating, themagnet 33 will be in position to influence the carrier and draw thelatter forward to close contacts 53 and 44. If the switch 55 is open atthis time, the heating circuit is not established, so that, aside fromthe need for properly positioning the iron on the rest, the user has theadditional safety factor of the manual control of the switch; with theiron properly positioned, and switch 53 closed, a controlled circuitwill be established through the heating element and temperature controlvia contacts 22 and 23 with contacts 43 and 4|. The desired temperatureof the iron is secured by manipulation of the temperature control,preferably prior to closing switch '56, so that through manipulation ofthe latter the user has complete manual control over the heatingactivity. As a result, the iron can be positioned on the rest when notin use, and even though carrier 5| may thereby be moved into contactposition by such positioning, the circuit remains inactive until switch56 is manipulated to closed position. Obviously, if the iron is notproperly positioned on the rest, and should have its heel bridgingcontacts 43 and 4|, no circuit activation will be present since magnet33 is not in position to move the carrier 56 to contact making position.

And, as is apparent, the fact that in positioning the iron on therestwith magnet 33 at the rear-the contacts 22 and 26 may be in contactengagement with contacts 40 and 4| prior to the iron reaching its restposition, does not present any material dangerous condition shouldswitch 56 be closed at the time. This is due to the fact that while thepower of magnet 33 is capable of reaching through space, the value ofthat power decreases as the distance between it and the armatureincreases, and since the carrier movement is opposedby the. tension ofsprings, 52, it. is obvious that. until the power value on the armature.by the approaching magnetv reaches a value sufficient to overcome thisspring tension, there will be no movement of the carrier, and thereforeno closing of the. circuit; this value is reached as the iron closelyapproaches its. rear position, and hence. the succeeding small travel ofthe iron will cause the. carrier advancing movement to be rapidlycompleted; with switch 56 open, the circuit will obviously be broken atthe switch, and while the magnet would attract the carrier, as pointedout, during such iron positioning, the circuit remains broken until theswitch is closed.

If desired, a resistor, not shown, may be inter- I posed in the lineleading, to post 58 to take care of any conditions of overload, thisbeing a wellknown expedient.

The rest is preferably provided with feet 61;, which may be of fibreconstruction.

As will be understood from the above detailed disclosure, the assemblageof sadiron and its rest when assembled for heating the iron, iscompletely under the control of the operator who retains switch 56 openuntil heating of the element 20. is to actually begin; hence, the restcan form a support for the iron when the latter is not in use. When theiron has been heated and removed from its rest it is free from allelectrical connections and is thus usable similarly to irons heated froman external source, with complete freedom of action, but having theadvantages provided by its ability to be controllably heated from anelectrical source. All of the elements for producing the latter actionare present in either the iron or the rest, but these are made activeonly when the iron has been properly seated on the rest, such seatingandthe manipulation of the switch 56completing the needed circuits, so thatthe operation is entirely within the control of the operator.

While I have herein shown and described a preferred form of assemblage,it is apparent that changes or modifications therein may be foundessential or desirable in meeting the various exigencies of use or theindividual desires of a user, and I hereby reserve the right to make anyand all such changes or modifications as may be found desirable oressential to these ends, insofar as the same may fall within the spiritand scope of the invention as expressed in the accompanying claims, whenbroadly construed.
